What B/B actually tests
B/B covers biology and biochemistry, with organic and general chemistry in supporting roles. It is the most experiment-driven section: passages routinely present novel studies, and the questions test whether you can connect your content knowledge to data you have never seen before.
Pure recall questions exist, but the section's center of gravity is application: reading a figure, tracking an experimental design, and reasoning one step past what the passage states.
Reading a 132 honestly
A 132 in B/B is in the 100th percentile on the official AAMC section table, in the upper part of the 118 to 132 scale. This is a strong section score, and on a retake the first job is protecting it.
If you are retaking for other sections, keep this one warm with light, regular practice rather than heavy re-study. Strong sections drop when they get ignored for months, not when they get maintained.
How Retakers move this section
B/B improvement on a retake tends to come from practicing the passage-to-question connection rather than re-watching content videos. If your content base held up, the leverage is in experimental reasoning and figure literacy.
The B/B Section Bank is the best official window into that skill, with the Biology Question Packs providing the volume work underneath it.
